Physics -- Unit One Kinematics Flashcards
1
Q
What is a Postion Time Graph (D-T Graph)
A
- describes the motion of an object
- with position on the vertical axis and time on the horizontal
2
Q
How do you find the average velocity on a D-T Graph?
A
find the SLOPE!!!!
3
Q
What if it’s curved?
A
Connect two points on the d-t graph with a line and find the SLOPE of that line, you will find the average velocity BUT ONLY BETWEEN THOSE TWO POINTS!!!!!!!!
4
Q
The average velocity in a straight line which is that specific time interval will have the same _____________ _____________
A
average velocity
5
Q
What is acceleration?
A
- Acceleration is the rate of change of velocity of an object over time. It tells us how quickly an object is speeding up or slowing down.
(ZERO ACCELERATION = MOVING AT A CONSTANT VELOCITY WHICH MEANS NO SPEED CHANGE)
